There May Be Another U.S. Ebola Case, This Time in Washington, D.C.

A patient with "Ebola-like symptoms" is being treated at Howard University Hospital, a hospital spokesperson toldNBC News on Friday.

The patient, who traveled to Nigeria recently, was admitted to the hospital in stable condition, and is being isolated and tested.

"In an abundance of caution, we have activated the appropriate infection control protocols, including isolating the patient," hospital spokesperson Kerry-Ann Hamilton told NBC News. "Our medical team continues to evaluate and monitor progress in close collaboration with the CDC and the Department of Health."

With the first U.S. Ebola diagnosis in Dallas, Texas this week, hospitals and health officials are on high alert to ensure that the deadly disease, which has killed almost 3,300 in West Africa, is contained.

It's possible this is a false alarm. In August, NYU grad student Eric Silverman was admitted to Mt. Sinai Hospital after he complained to doctors of "flu-like symptoms all too familiar to Ebola victims — a high fever, a sore throat, headache and diarrhea. Silverman had just returned from Sierra Leone in West Africa, where he had been doing humanitarian aid. The hospital isolated Silverman before an Ebola diagnosis came back negative.

Howard University Hospital did not share any more details about the patient with the press, but the hospital "will provide updates as warranted."
